25. Node.js is a platform built on Chrome's
    JavaScript runtime for easily building fast,
    scalable network applications. Node.js
    uses an event-driven, non-blocking I/O
    model that makes it lightweight and
    efficient, perfect for data-intensive real-time
    applications that run across distributed
    devices.
